The Big Bang Theory star got her Jedi on at the Longines Masters in Los Angeles on Saturday. Light saber and all, Cuoco dressed as Luke Skywalker to compete in the Pro-Am Style & Competition for Charity equestrian event.

Cuoco wasn't the only one dressed in Star Wars gear -- she brought an entire costumed crew with her! Her teammate, Tracy Wade, even dressed as Darth Vader, and another pal donned a full Chewbacca costume. The getups were apparently good luck, as she and Wade were crowned the Charity Pro-Am Style & Competition winners.

The 29-year-old actress later took to Instagram to share some highlights from her epic night.

"Had an amazing night with my Star Wars team at the @mastersgrandslam charity class benefitting #rideon!!!!" she wrote.

The event Cuoco competed in was a team class composed of one professional rider and one amateur rider. Eight teams, all competing for a charity of their choice, dressed up in costumes of their choice, like Alice in Wonderland and Wizard of Oz, as they rode to a music selection complimenting their theme. Each team was judged on the number of penalties over the fences, the horse's style and the team's style and elegance by a celebrity jury composed of Denise Richards, Perrey Reeves and KTLA anchor Sam Rubin. Cuoco and Wade's win benefitted the non-profit organization Ride On.

The evening also featured the inaugural Gucci Gold Cup, where 36 of the world's best riders jumped the course designed by Luc Musette. Bill Gates, Bruce Springsteen and Patti Scialfa cheered on their daughters, and Camilla Belle, Jeannie Mai, Carly Steel, Alison Sweeney and Jean Claude Van Damme were also in attendance.
